The present condition of the present drinking water is purifying to the level which is harmless by each country in accordance with an original guideline by what called the drinking water quality guideline which WHO (World Health Organization) took out.
The once cause of water pollution was what is depended on industrial drainage or industrial waste. It is the cause that home drainage is big, now. There are many rates which synthetic detergent and kitchen drainage are polluting especially.
In developing countries, industrial drainage has come out mostly like an old advanced nation. There are also many districts where orderly sewer maintenance is not carried out, and there are not few places which safe drinking water does not get.
Problem
Although the life improvement of an individual is called for, it is a rather difficult thing that every person raises the consciousness.
Moreover, the water pollution of a river eutrophication has spread in Indonesia which cultivates the shrimp, for example. The shrimp which grows up here is an object for export, and Japan also occupies many. This is a typical problem that a help of an advanced nation is required. (Refer to Deforestation and mangrove wood destruction)
Measure
In Japan, the fine standard is defined about the water quality of factory effluent based on Water Pollution Control Law. However, the standard to drainage from the household is behind in the measure. Individual consciousness is becoming important.
